BACKGROUND

The present disclosure is directed to a product dispenser, particularly, a deodorant product dispenser. More particularly, the present disclosure is directed to a reusable product dispenser with a deodorant refill cartridge allowing for the cartridge to be changed without disposing of the whole product dispenser.

Dispensers for dispensing solid, liquid, and/or gel deodorant products are known. Typically, the product is extruded out of an outlet in a top end of the dispenser until the product is completed. The product dispensers are limited to single use, and after completion of the product within the dispenser, the consumer is left with no other option but to dispose of the empty dispenser and purchase a new, full, product dispenser.

A problem with this type of single-use product dispenser is that its single-use nature leads to excessive waste, thereby raising costs of manufacturing and reducing efficiency.

An approach to solving this problem of over-production of the product dispensers, as well as the effects on the manufacturing plants, is to create a reusable product dispenser that allows for the consumer to only purchase deodorant refill cartridges instead of complete product dispensers. This also allows manufacturers to use less material in production of replacement deodorant refill cartridges, than previously used.

Embodiments of the presently disclosed deodorant dispensing apparatus, including a reusable product dispenser and a deodorant refill cartridge thereof, are described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views.

As used herein, the term “distal” refers to that portion of the deodorant dispensing apparatus deodorant refill cartridge and its components that is closer to a user's body when in use (for example, further from the user's hand when in use), while the term “proximal” refers to that portion of the deodorant dispensing apparatus and its components that is further from the user's body when in use (for example, closer to the user's hand when in use).

As used herein, the term “user” refers to any individual seeking to apply a product to their body. In the following description, well-known functions or construction are not described in detail to avoid obscuring the present disclosure in unnecessary detail. Additionally, as used herein, the term “deodorant” refers to any deodorizing product which may include for example, perfumes, colognes, lipstick, cosmetics, ointments, antiperspirants, or any combinations thereof which may include those in liquid, gel, solid, powdered form, or any combinations thereof.

As will be described in detail below, provided is a deodorant dispensing apparatus which includes a reusable product dispenser and a deodorant refill cartridge, where the deodorant dispensing apparatus is configured to allow for selective insertion and removal of the deodorant refill cartridge to and from the reusable product dispenser.

Referring initially to FIGS. 1A-1C, the deodorant dispensing apparatus 100 includes a reusable product dispenser 200 and a deodorant refill cartridge 300. The deodorant refill cartridge 300 may be at least partially inserted into, and releasably coupled to, the reusable product dispenser 200. The deodorant refill cartridge 300 is configured to house a deodorant product therein. When the deodorant refill cartridge 300 is coupled to the reusable product dispenser 200, the reusable product dispenser 200 can be manipulated to dispense the deodorant product from the deodorant refill cartridge 300. Upon depletion of the deodorant product housed within the deodorant refill cartridge 300, the deodorant refill cartridge 300 can be disposed of (or refilled with new deodorant product for subsequent use) and a new (or refilled) deodorant refill cartridge 300 can be coupled to the reusable product dispenser 200 for continued use. Each of the reusable product dispenser 200 and the deodorant refill cartridge 300 will be described in turn.

With reference to FIGS. 2A-2B, the reusable product dispenser 200 includes a cylindrical housing 210, a base 220, a telescope 230, and a spring 240 disposed between the base 220 and the telescope 230. In aspects, the reusable product dispenser 200 additionally includes a cover 250 and a base cover 270. The cylindrical housing 210 defines a longitudinal axis X-X (FIG. 1A). The base 220 is rotatably coupled to the cylindrical housing 210 and configured to rotate relative to the cylindrical housing 210 about the longitudinal axis X-X in a first direction (indicated by arrow A in FIG. 1A) and a second direction (indicated by arrow B in FIG. 1A). The telescope 230 is operably coupled to the base 220 such that rotation of the base 220 about the longitudinal axis X-X in either the first or second direction, causes corresponding rotation of the telescope 230 about the longitudinal axis X-X in the same direction. The spring 240 biases the telescope 230 away from the base 220.

The cylindrical housing 212 is configured to receive at least a portion of the deodorant refill cartridge 300 therein. The cylindrical housing 210 includes a latching mechanism receiver 212 configured to receive and releasably engage a portion of the deodorant refill cartridge 300 and secure the deodorant refill cartridge 300 to the cylindrical housing 210. In particular, the latching mechanism receiver 212 of the cylindrical housing releasably engages the latching mechanism 316 (FIG. 4) of the deodorant refill cartridge 300. In an aspect, the latching mechanism receiver 212 is disposed on a distal portion 210 b of the cylindrical housing 210 and the latching mechanism 316 is disposed on a distal portion of the deodorant refill cartridge 300.

Additionally or alternatively, the latching mechanism receiver 212 of the cylindrical housing 210 may include a first latching mechanism receiver 212 a (FIG. 5B), to engage a first latching mechanism 316 a (FIG. 3B) of the deodorant refill cartridge 300, and a second latching mechanism receiver 212 b (FIG. 5B), to engage a second latching mechanism 316 b (FIG. 3B) of the deodorant refill cartridge 300, disposed on opposite sides of the cylindrical housing 212.

The cylindrical housing 210 may additionally include a level indicator 214 (FIG. 5B) disposed along a portion of an outer wall of the cylindrical housing 210 and configured to provide a view through the outer wall of the cylindrical housing such that components disposed within the cylindrical housing 210 may be visible. For example, the level indicator 214 of the cylindrical housing 210 may provide visibility of the deodorant refill cartridge 300 (or any components thereof), when the deodorant refill cartridge 300 is coupled to the cylindrical housing 212.

The cylindrical housing 210 may include a notch 218 for coupling the base 220 to the cylindrical housing 210. The notch 218 may be disposed at the proximal portion 210 a of the cylindrical housing 210. In an aspect, the notch 218 of the cylindrical housing is configured to mate with a locking mechanism 228 of the base 220 to couple the base 220 to the cylindrical housing 218. In an aspect, the locking mechanism 228 of the base 220 is configured to mate with the notch 218 of the cylindrical housing 210 such that the base may be releasably coupled to the cylindrical housing 210. Additionally or alternatively, the locking mechanism 228 of the base 220 may be configured to permanently mate with the notch 218 of the cylindrical housing 210. In either aspect, the base 220 is rotatable relative to the cylindrical housing 210.

The telescope 230 is disposed within the cylindrical housing 212 and longitudinally movable relative thereto. The cylindrical housing 210 includes a stop member 219 configured to prevent further distal longitudinal movement of the telescope 230 relative to the cylindrical housing 212 (as the telescope 230 is biased distally by the spring 240) when a flange 234 of the telescope 230 engages the stop member 219. In an aspect, the stop member 219 of the cylindrical housing 210 is disposed at the proximal portion 210 a of the cylindrical housing 210. Additionally, in an aspect, the stop member 219 is disposed on, or along, an inner wall of the cylindrical housing 212. As illustrated in FIG. 2B, the stop member 219 prevents distal advancement of the telescope 230 when the flange 234 of the telescope 230 engages the stop member 219. In an aspect, the flange 234 is a tab that protrudes orthogonally from the telescope 230 at one point along the circumference of the proximal portion 230 a of the telescope 230. Alternatively, the flange 234 may span the entire circumference of the proximal portion 230 a of the telescope 230 and have an outer diameter that is larger than the outer diameter of the proximal portion 230 a of the telescope 230.

The base 220 of the reusable product dispenser 200 includes spring holster 226 configured to support the spring 240 therein. The spring holster 226 of the base 220 may be disposed centrally within the base 220 and is configured to receive the proximal portion 240 a of the spring 240. A distal portion 240 b of the spring is operably coupled to the telescope 230 and biases the telescope 230 away from the base 220. Thus, the spring 240 of the reusable product dispenser 200 is disposed between the base 220 and the telescope 230 and biases the telescope 230 distally along the longitudinal axis X-X. The distal portion 240 b of the spring 240 is disposed adjacent the inner wall 230 i of the telescope 230 and proximal portion 240 a of the spring 240 is disposed within the spring holster 226 of the base 220. The spring 240 is in a decompressed state prior to installation of the deodorant refill cartridge 300 into the reusable product dispenser 200 and is in compressed state after installation of the deodorant refill cartridge 300 into the reusable product dispenser 200.

The spring holster 226 also defines at least one slot 222 to mate with an inner rib 236 of the telescope 230. The slot 222 of the base 220 is configured to operably mate with the telescope 230 such that rotation of the base about the longitudinal axis X-X causes corresponding rotation of the telescope 230 about the longitudinal axis X-X in the same direction. In an aspect, the telescope 230 includes a rib 236, disposed on an inner wall 230 i of the telescope 230, configured to slide within the slot 222 defined by the base 220. The telescope 230 may be coupled to the base 220, within slot 222, such that the telescope is freely movable in a longitudinal direction along longitudinal axis X-X (e.g., distally and proximally). The rib 236 extends from a proximal portion 230 a of the telescope 230 to a distal portion 230 b of the telescope 230. Although described and illustrated as the telescope 230 including a rib 236 and the base 220 defining a slot 222, it is understood that the base 220 may include a rib and the telescope 230 may define a slot.

The base 220 may include a base cover 270. The base cover 270 may include at least one interlocking protrusion 272 (FIG. 8A) disposed on an inner wall 270 i of the base cover 270 configured to mate with at least one interlocking recess 224 (FIG. 6A) of the base 220. Movement (e.g., rotation) of the base cover 270 causes corresponding movement of the base 220 via the relationship between the interlocking protrusion 272 and the interlocking recess 224. Although shown and described as the base 220 including an interlocking recess 224 and the base cover 270 including an interlocking protrusion 272, in an aspect, the base 220 includes a protrusion and the base cover 270 includes a recess.

As described above, the proximal portion 230 a of the telescope 230 is operably coupled to the base 220 and the telescope 230 is biased away from the base 220 via spring 240. As described in further detail below, a distal portion 230 b of the telescope 230 is configured to operably couple to a portion (for example, the refill plunger 320) of the deodorant refill cartridge 300.

The plurality of detents 232 of the telescope 230, defined on a distal portion 230 b of the telescope 230, is configured to mate with a refill plunger 320 of the deodorant refill cartridge 300 when the deodorant refill cartridge 300 is coupled to the reusable product dispenser 200. In particular, at least one of the plurality of detents 232 mate with a proximal rib 328 (FIG. 10C) of the refill plunger 320. The plurality of detents 232 of the telescope 230 is configured to couple to the refill plunger 320 of the deodorant refill cartridge 300 such that rotation of the telescope 230 about the longitudinal axis X-X causes corresponding rotation of the refill plunger 320 about the longitudinal axis X-X. In an aspect, the plurality of detents 232 are defined along an outer wall 230 o of the distal portion 230 b of the telescope 230. Although illustrated and described as including a plurality of detents 232, telescope 230 may include only a single detent thereon.

The telescope 230 may be a single structure or may be a multi-component structure defined by a plurality of telescoping sub-components, configured to vary a length of the telescope 230 and transition between a first condition (having a shorter length) and a second condition (having a longer length). The first condition of the multi-component structured telescoping telescope 230 can have a minimal length and the second condition can have a maximum length.

The reusable product dispenser 200 may further include a housing sleeve 260. The sleeve 260 may wrap around the cylindrical housing 212. The housing sleeve 260 includes at least one latching mechanism opening 262 (FIG. 9B) thereon. The latching mechanism opening 262 may be disposed on the distal portion 260 b of the housing sleeve 260 and may have a shape corresponding to the shape of the latching mechanism receiver 212 of the cylindrical housing 212. The opening 262 allows a user to access the latching mechanism 316 of the refill barrel 310, when the deodorant refill cartridge 300 is coupled to the cylindrical housing 210. The housing sleeve 260 includes a cylindrical opening on both the distal portion 260 b and proximal portion 260 a for positioning the cylindrical housing 212 therethrough. The sleeve 260 may be a single component sleeve or a multi-component sleeve including decorative elements thereon.

Deodorant dispensing apparatus 100 may also include a cover 25. The cover 250 includes an inner wall configured to operably couple to a distal portion 210 b of the cylindrical housing 210. The inner wall of the cover 250 may be threaded or threadless. Additionally or alternatively, the cover 250 may be configured to operably couple to a distal portion 260 b of the housing sleeve 260.

Having described above the components of the reusable product dispenser 200, the components of the deodorant refill cartridge 300 will now be described in detail with reference to FIGS. 3A-3B and FIG. 4. The deodorant refill cartridge 300 includes a refill barrel 310 and a refill plunger 320 operably coupled to the refill barrel 310. The deodorant refill cartridge 300 may also include a cap 330. The refill barrel 310 of the deodorant refill cartridge 300 defines a cylindrical opening 312 (FIG. 10A), configured to retain a deodorant product 400 therein. As described above, the deodorant refill cartridge 300 is configured to releasably couple to the reusable product dispenser 200. When coupled to the reusable product dispenser 200, the deodorant refill cartridge 300 can be controlled to disperse an amount of the deodorant product 400 retained within the deodorant refill cartridge 300.

The refill barrel 310 includes a threaded inner wall 314 configured to mate with the threaded outer wall 324 of the refill plunger 320 such that rotation of the refill plunger 320 about the longitudinal axis X-X causes simultaneous distal advancement of the refill plunger 320 along the longitudinal axis X-X. The cap 330 is configured to operably couple (for example, removably couple) to the distal portion 310 b of the refill barrel 310 to retain the deodorant product therein.

As described above, latching mechanism 316 of deodorant refill cartridge 300 is configured to mate with latching mechanism receiver 212 of reusable product dispenser 200 to releasably couple the deodorant refill cartridge 300 to the reusable product dispenser 300. The latching mechanism 316 may include a first latching mechanism 316 a (FIG. 3B) and a second latching mechanism 316 b (FIG. 3B), disposed on opposite sides of the distal portion 310 b of the refill barrel 310 for releasably coupling the refill barrel 310 to a reusable product dispenser 200. Latching mechanism may include a finger recess 318 (FIG. 3B) to conform to the shape of a user's finger. In particular, in an aspect, latching mechanism 316 a couples to latching mechanism receiver 212 a and releases from latching mechanism receiver 212 a when a user applies pressure to the latching mechanism 316 a. Additionally, in an aspect, latching mechanism 316 b couples to latching mechanism receiver 212 b and releases from latching mechanism receiver 212 b when a user applies pressure to the latching mechanism 316 b.

The refill barrel 310 may include a level indicator 317 (FIG. 10B) disposed thereon. The level indicator 317 is configured to provide a view into the refill barrel 310 such that a user may view an amount of the deodorant product 400 remaining in the refill barrel 310. Additionally, the level indicator 317 of refill barrel 300 is positioned such that when the deodorant refill cartridge 300 is coupled to the reusable product dispenser 200, the level indicator 317 aligns with the level indicator 214 (FIG. 5B) of the cylindrical housing 200. With this aligned arrangement, a user may visualize the amount of deodorant product 400 remaining, even with the deodorant refill cartridge 200 is coupled to the reusable product dispenser 300.

The distal portion 310 b of the refill barrel 310 may include a curved (e.g., rounded) edge 319 (FIG. 10B). The curved edge 319 provides the dual function of providing a stable connection between the deodorant refill cartridge 300 and the reusable product dispenser 200 and providing a smooth surface so as to not irritate a user's skin during use. The curved edge 319 may be formed by rounding the distal portion 310 b of the refill barrel 310 by any suitable method including, but not limited to, bending or heat treating the distal portion 310 b. In aspects, the curved edge 319 has a diameter larger than a diameter of the refill barrel 310 (e.g., a proximal portion 310 a of the refill barrel 310).

The refill plunger 320 includes the threaded outer wall 324, at least one distal rib 326 disposed on a distal portion 320 b (FIG. 10B) of the refill plunger 320 and at least one proximal rib 328 disposed on a proximal portion 320 a of the refill plunger 320. The at least one distal rib 326 is configured to engage with the deodorant product 400 disposed within the cylindrical opening 312 of the refill barrel 310 (FIG. 10A). In this manner, rotational movement of the refill plunger 320 about the longitudinal axis X-X causes corresponding rotational movement of the deodorant product 400 engaged therewith along the longitudinal axis X-X. The at least one proximal rib 328 of the refill plunger 320 is configured to mate with the plurality of detents 232 (FIG. 7B) of the telescope 230 such that rotational movement of the telescope 230 about the longitudinal axis X-X causes corresponding rotation of the refill plunger 320 about the longitudinal axis X-X. With the refill plunger 320 engaging both of the deodorant product 400 (via distal rib 326) and the telescope (via proximal rib 328), the deodorant product 400 may be dispersed through the refill barrel 310 upon control of the telescope 230.

The refill plunger 320 defines a plunger opening 322 therethrough and is configured to receive deodorant product 400 in the molten state therethrough. In particular, when the refill plunger 320 is coupled to the refill barrel 310, the plunger opening 322 is used to introduce the deodorant product 400 into a chamber defined within the refill barrel 310. The liquid/gel product takes the shape of the refill barrel 310 and is retained therein in a solid, liquid or gel state. Additionally or alternatively, the plunger opening 322 may include a seal e.g., foil seal or any other capping structure to close the plunger opening 322. As described above, rotation of the refill plunger 320 in a first direction about the longitudinal axis X-X causes distal translation of the deodorant product 400 along the longitudinal axis X-X out of the distal portion 310 b of the refill barrel 310. Similarly, rotation of the refill plunger 320 in a second direction about the longitudinal axis X-X may cause proximal translation of the deodorant product 400 along the longitudinal axis X-X.

In an aspect, the refill barrel 310 includes an inwardly facing annular lip 313 (FIG. 10D) disposed on a proximal portion 310 a thereof. The annular lip 313 has a diameter smaller than the inner diameter of the proximal portion 310 a of the refill barrel 310 and prevents the refill plunger 320 from protruding out of the proximal portion 310 a of the refill barrel 310. During manufacturing, the refill plunger 320 may be inserted into the cylindrical opening 312 of the refill barrel 310 and rotated therein until the refill plunger 320 is stopped by the annular lip 313. Additionally, the refill plunger 320 may define an opening 329 (FIG. 11E) configured to latch with a snap latch 315 (FIG. 10B) of the refill barrel 310 when positioned in (e.g., rotated to) the proximal portion 310 a of the refill barrel 310.

The cap 330 of the deodorant refill cartridge 300 is configured to operably couple to the distal portion 310 b of the refill barrel 310. The cap 330 may include a lip 334 (FIGS. 12A-12C) extending outwardly from the cap 330 configured to rest on the curved edge 319 (FIG. 10B) of the refill barrel 310 and a tab 336 configured to allow for removability from distal portion 310 b of the refill barrel 310. The cap 330 may include at least one aperture 332 disposed on distal portion 330 b of the cap 330 configured to allow liquid/gel deodorant product 400 to be dispensed therethrough.
